SPECIFICATION forming part of .Letters Patent No. 655,258, d.ated.'.ttufgu-St` 7, 1900 Application filed February 24. 1900. Serial No. 6,368. (No model.)

T all whom, t may concern.-

Be it known that I, VINCENT A. MENUEZ, a citizen of the United States,residing at Memphis, Shelby county, Stateof Tennessee, have invented certain new and useful Improvements in Vapor-Lamps, of which the following is a speciiication.

My invention relates in general to improvements in oil or gasolene lamps of the vaporizer type, but especially to that class of such lamps in which the oil is stored in a reservoir, from which it is forced by Acompressed air or is allowed to liow by gravity through suitable distributing-pipes to the lamps.

The objects of my invention are to im prove the lamp in general and in detail and at the saine time toreduce the cost of the lamps. I accomplish these objects, first, by providing a simple, cheap, and effective extensiontube to permit access to the lamp for lighting and adjustment; second, by providing means for the initial generation of gas; third, by providing an improvedmiXing-tube; fourth, by providing an improved burner; fifth, byproviding an improved shade-holder; sixth, by providing an improved deflecting-cap for the chimney to concentrate the heat from the chimney on the generator; seventh, by providing an improved'foim of storage-tank; eighth, by an improvement in the construction of the needle-valve, and, last, by the gen-` eral improvement in details and by the novel combination of parts hereinafter set forth in the specification, drawings, and claims.

In the drawings, which show the preferred form of my lamp, Figurel'is a section on the centerline of one of myimproved lamps. Fig. 2 is a section on the center line of theupper stuffing-box of the extension-pi pe. Fig. 3 is a like section of the lower stuffing-box, showing a slight modification from the same box in Fig. 1. Fig. 4 is a section on the line B B of Fig. -1 to show attachment of the extensionlock. Fig. 5 is a section on the line A A of Figs. 1 and 4 to show locking-spring. Fig. 6 is a plan of the air-inlet of the mixing-tube, looking in the direction of the arrow O, Fig. 1. Fig. 7isasection of theburner-cap. Figs. 8 and 9 are a plan and section, respectively, of a modification of the burner-cap. Fig. 10

is a section of my improved storage-reservoir,

with compressed air to force out the gasolene and aerate same prior to generation of the gas. Fig. 11 is a view of a double lamp with a modified form of mixing-chamber shown in section. Figs. 12 and 13 are details of a valve. Figs. 14, 16, and 17` are details of the initial generator. Fig. 15 is a detail of the needlevalve. Fig. 18 shows a view of an old form of extension-bracket which may be used. Figs. 19 and 20 are details of the Vshade-holder. Figs.' 21, 22, and 23 are a plan and two sections of the heat-deflector or chimney-cap.

Fig. 24 is a form of separate storage-reser- .vor with attached air-pumps. `voir may be placed out-side of the buildings This reseror buried in the ground, if desired.

Referring now to the drawings, in which like numerals denote the same or like parts in all the views and confining the description at first to the single-burner lamp shown in Fig. 1, 1 is a hollow curved tube forming one side of the lamp-frame and serving at the same time as a gas-chamber, being virtually the same design as that claimed in my pending application, Serial No. 719,601, filed June 6, 1899. Opposite this tube 1 isa similar tube 2, closed, however, at both the upper and lower ends, which also forms a part of the frame. These tubes are united at4 their lower ends in a substantially Y-shaped piece 3, which encircles both the pipes 1 and 2 and is brazed to them. At their upper ends these pipes are fastened to a yoke made up of the two tubes 4 and 5, which are in turn joined together in a Thinto which is also fastened an oil-tube 7, leading to the oil-reservoir S, Fig. 10, or Sa, Fig.'24. The pipe 4 isclosed by a plug 9 and the oil compelledtoiiow through the pipe' 5 to the generator. After passing through the Y-piece 3 the pipe 1 terrninates in a vertical cylindrical portion V10,

(see Fig. 11,) the piece 3 forminga collar at the lower end of this vertical portion. Over this vertical cylindrical portion 10 is slipped a burner, made up of a short section of pipe 11, integral with which 4is an iuverted-cup-shaped piece 12, which terminates in a horizontal portion 13, on which the chimney 14 rests. Under this horizontal portion 13 lugs 15 are provided to hold the mantle-support 16 and the chimney-holders 17. The cupshaped piece 12 has air-holes 18 through it, which holes are opened or closed by a close-fitting IOO tle 23, as shown in Fig. 8, and at the sametime leave spaces tol permit the entrance of air betweenthe cap and mantle to steady the mantle and provide air for combustion.

Fig. 9 illustrates a modified form of cap-20, in which the deflecting-plate 22a is sunk in the cap instead of being placed above it, as

in Fig. 7. While the holes 21 shown are separate and distinct, it is not essential that such should be the case, the ordinary form of wirenetting caps with the detlecting-plates serving quite as well.

The closed tube 2 terminates at its upper end in a horizontal portion, through which is centrally fastened a generator 65. Thisgenerator extends through the bend in the pipe 2 and has a stuffing-box 27 and hand-wheelv 28l at the opposite end. This generator 65 extends centrally across the center line of the burner below, by which itis heated, and is here surrounded by a tube 26, which serves as the gas-generator for the lamps. Extending past the center line of the burner the generator 26 terminates in -a mixing-chamber 29, which chamber-surrounds the upper end of the gas-chamber l and the said generator 26, the centers of the generator 26 and this gaschamber 1 being in line.

A deecting-cap 30 (see also Figs. 21 to 23) concentrates the heat from the burner on the needle-valve generator 26, while a reliector 3l also helps to concentrate the heat thereon. The ends ofthe cylinder 29 are perforated f with holes 32, which are closed or opened by air.

the rotation of the cap 33. If desired, this box may be made rectangular in form instead of cylindrical, in which case it is preferably made a cube with the needle-valve and vaport-ube `entering opposite sides. Two or more of the free sides or ends of the box may be perforated, as were the ends of the cylinder, and, as init, the air-opening regulated by the rotation Aof a perforated circular cap 33. This mixing-chamber may be rotated around the generator 26 and gas-chamber 1 as an axis in case drafts should tend to disturb the How of By rotating this chamber properly the lampv can be4 placed in an exposed position without danger of any disturbance of this kind.

29a, Fig. 11,\is amodified form of mixingchamber. This chamber is substantially bellshaped, and the admission of 'air is regulated as. in'the first case.

As a means of starting the initial-generation of 'gas in the generator 26 I provide an oil or alcohol containing receptacle, prefer-v This cap' ably uned with asbestos or like not-@embustible material which is saturated with cornbustible fluid, which receptacle is fastened to the under side of the side frame 2 in such manner that it can be brought under the generator without detaching it from the frame 2 and so disposed under the frame 2 that when swung out of use the flame is extinguished by the said frame. I illustrate this heater 34 in two slightly-modified forms. That shown in Fig. l is pivoted and swings around into the dotted position 35. The open topis the same as that shown at 36 in Figs. 16 and 17. This opening 36 is closed by the frame 2 when swung under same. In the modified form the heater 34 slides in andout in a hollow tube 37, the flame beingextinguished by drawing the heater 34 back into the tube 37. Since the heater 34 when extended is still under the center of the needle-valve, it would be extremely difficult to fill the said heater when it was exhausted. I provide, therefore, a slot 38 near the end of the tube 37, which permits the heater to be rotated to the dotted position shown for filling. Y

In order to reach the lamp for filling or lighting and to bring'it lower for use, if so desired, I provide an extension supply-tube,

' consisting of an outer tube 7, fastened to the down tubes 4 and 5 at its lower end and having at its upper end a stuffing-box which slides on an inner tube 39. This inner tube leads to the oil-tank reservoir, from which it maybe shut olf by a valve 40, and has `at its lower enda stuffing-box sliding on thezinside of the tube 7. These stuffing-boxes consist of tight collars 41 and 41, attached, respectively, to the upper end of the tube 7 and lower endof the tube 39, double iiexiblc packing-washers 42, separated by a loose collar 43, the whole being held by adjustable nuts 44 and 44a, which force the exible packing. These stung-boxesv ing loosened;

`When the lamp is pushed to its highest position, being that shown, itis held up by a catch 46, which catches under a collar 45 on thenut 44. l This catch 46 is pivoted `on a collar 47, clamped to the tube 39, and is held against the `collar 45 by a spring 48, also clamped tothe collar 47. A cord or wire 49, depending from the other end of the catch 46, serves as a means of lreleasing the catch' when thetube is to be lowered. It will be noted that the collar, Fig. 4, is clamped to the tube 39and may be adjusted by Aloosening a cap-screw and sliding the collar to the point desired. This enables `the heightof the lamp when raised to be adj ustedito varying heights of ceiling or `other conditions. This form of extension, while described `for a vvertical drop, lmay also be used in connection with a bracket fastened to the wall or,'in yfact, anyhorizontal pipe as a horizontalfexf IOO tension, and may be used with gas-lamps of the ordinary type as well as with vapor-lamps, and I wish the claims covering this extension to be read ascovering a horizontal as Well as a vertical drop and to be not limited to a vapor-lamp, but to include all forms of gaslamps and brackets as well. As an alternate extension to be used with the other parts of the lamp, if so desired, I show a flexible tube Fig. 18, connecting the pipes 39 and 7; but no, claim is made to this extension in itself, as it is old;A It is shown merely to illustrate the fact that I do notwish to" confine the use of the other and novel partsshown to one consists of a band 51, surrounding but not touching the chimney 14, (shown by the dotted lines,) which has three arms 52 out underneath the band 5l and bent out therefrom. To these arms are riveted the shade-clips 53, having'a portion of their lower ends bent out to support the shade and a projection 54 on their side to steady them against the chimney. These shade-holders rest on the chimney at three points 55 and at these points only, thus bringing only three points instead of the entire band in contact with the glass chimney.

Fig. 24 illustrates the ordinary form of oilstorage reservoir, in which 8f* is the reservoir, and 56 the air-pump. A pressure-gage and thumb-valve for filling the tank are also shown in the figure. This reservoir may be placed in any part of the building, or, if so desired, may be placed outside of the building or buried in the ground.

Fig. IO shows a special form of reservoir on the supply-pipe 7. In this view I have shown a lamp Without extension, the same being lowered--reservoir and all-for illing. In this view, then, S is a storage-tank, 57is an airvalve adapted to be connected to any ordinary form of air-pump, (notshowm) and 58 ascrewcap to permit filling. The pipe 7 passes entirely through the reservoir 8 and is brazed to it top and bottom. A small pipe 59 starts near the bottom of the oil-reservoir S and extends up and into the pipe 7, the joint beingbrazed where the smaller pipe enters the larger one. In this construction the air above the oil in thereservoir forces the oil upward through the pipe 59 into the pipe where it is partially vaporized and then descends by gravity to the vaporizer or needle-valve generator 26. I thus obtain, with a close-connected reservoir, the advantages of air aeration and at the same time avoid the large shadow inevitably cast by a reservoir placed below the lamp. The air forced into the reservoir over the oil or other hydrocarbon liuids admixes intimately with them in passing downward through the fluid to the mouth of the feed-pipe 59.

ciated with a hydrocarbon fluid absorbs some of the fluid in the form of vapor and carries with it other particles mechanically mixedJ Air thus intimately asso- It passes upward through the feed-tube 59 and is discharged upward in the tube 7, becoming thus further vaporized. It descends thence through the pipe 7 to the generator 26, where it is converted into gas. I thus secure a mixture of air and vapor before generation and materially assist the mixing of the air and gas for burning. Since in hydrocarbon-lamps we have a mixture of about fifteen per cent. gas and eighty-five per cent. air, this is of material importance. In gravity-lamps this mixture must be made at the burner and can thus not be as thorough as in my lamp. I secure a more intimate mixture and a corresponding more combustible compound, which insure a more perfect, instantaneous, and thorough combustion and materially increases the heating and illuminating power over that obtainable in gravity-lamps.

Figs. 12 and 13 are two sections of a combined T and valve for use in a lamp, in which 6l is a T, in which the opening connecting the part of the T at right angles is reduced to a small passage 62 and has crossing it a conicalshaped hole adapted to be closed by a likepointed valve 63, the T also having a stuffingbox 64, substantially as shown, arolind the valve-rod 63. i

Fig. 15 illustrates a special form of needlepoint for a needle-valve. In this, 65 is the valve stem, made of some comparativelycheap metal, as brass, 66 the valve-cap, having a small hole therein, and 67 the needle, adapted to pass through the opening in the cap and keep the same clear of carbon. My improvement consists in inserting a needle 67, of aluminium, German silver, or other noncorrosive metal, in the valve-stem, where both are large enough to make a good joint, and in making the point of the needle of the curved form shown to give it sufficient strength to stand up under it-s work.

Fig. 1l shows a modification consisting of putting two of the curved tubes l together to form a double lamp. One or more of these tubes may be added to forma lamp of three or more burners. Especial attention in both cases is called to the easy curve of the gastube 1, there being absolutely no sharp angles to check the .flow of the gas.

While I have shown and described in this specification a series of parts adapted to be used together in a lamp, I wish it distinctly understood that in so showing them in combination I do not thereby limit myself to the use of all of them at the same time, and I also make this application with the distinct understanding that if at any time I desire to cut out any part or change any detail such omission or change shall not alect those claims of the. patent in which said parts or details were not embodied.

The broad idea of avapor-conducting pipe adapted to carry the burner and arranged with its other end in alinement with a needlevalve generator is described and claimed in my pending application, Serial No. 719,601,
